Daniel Palacios is a Spanish voice actor best known for his extensive work on the Dragon Ball franchise in the Spain dub. His career is closely associated with the series, where he has voiced multiple prominent characters across various installments.

Palacios is the voice behind the character Majin Buu in several series and films, including Dragon Ball Super and Dragon Ball Z: Battle of Gods. He has expressed a particular fondness for this role, citing Buu as his favorite character to portray. He found the character more playful than others and appreciated the challenge of creating distinct voices for Buu's different forms.

In addition to his work as Majin Buu, Palacios is also the voice of Tenshinhan (known as Tensián or Ten Shin Han in the Spanish dub) in the franchise. He assumed this role early in the original Dragon Ball series, taking over from another actor starting with episode 86. He continued to voice Tenshinhan throughout Dragon Ball Z, as well as in several films such as Dragon Ball Z: Bojack Unbound, Dragon Ball Z: The Tree of Might, Dragon Ball Z: Battle of Gods, and Dragon Ball Z: Resurrection 'F'.

Beyond Dragon Ball, his voice acting credits include a role in the series Dragon Quest: Dai no Daibōken, where he played Abuelo Blass. He has also voiced the character Shisami in Dragon Ball Super.

Regarding the voice acting process, Palacios has reflected on the demanding nature of dubbing a long-running series like Dragon Ball. He noted that a key challenge is the need to accurately recreate a character's voice even after long periods of absence, and he recalled that scripts from the early days of the series were often incomplete, requiring actors to improvise based on context. He has also commented on his surprise at the enduring popularity and longevity of the Dragon Ball franchise, a phenomenon he did not anticipate when he first began working on the series.
